This plane's ground speed looks slower than a person's walking speed, maybe 10km/h!? It can not be possible that an airflow of 10km/h around wings keep plane in the air. What is the key for such a slow flight? a) head wind b) blast from propeller…

How is it possible, and why? Why is the aircraft not overspeeding? I understand it has beta thrust, so would that be an explanation? What are the advantages to such a steep approach?
